I have this same issue. In the past all I had to do was boot into test mode then delete the gpspara.bin files then it would be resolved, but now my unit won't go into test mode. It just keeps rebooting at the startup screen. Help please

Will this work for the 700? What's the stylus? This is what I'm getting: Start the truck, unit goes to the "Pioneer" screen, the for 5-7 seconds goes to the "main menu" screen with start up note over it. After 5-7 seconds, goes back to "Pioneer" screen for 20 seconds, and the cycle continues..... Is this what you all are talking about??
